Abstract

Background: Atopic keratoconjunctivitis (AKC) and vernal keratoconjunctivitis (VKC) are chronic inflammatory allergic diseases that are associated with some common conjunctival and corneal complications. 1 The clinical corneal manifestations of both entities may include superficial punctate keratitis, macroerosions, corneal ulceration, plaque formation, corneal neovascularization, and lipid infiltration. Purpose: To quantitatively evaluate the early ocular surface inflammation before and after mitomycin C (MMC)-aided papillary resection in severe allergy patients with corneal complications. Methods: Three eyes with VKC and 5 eyes with AKC were included in this study. All eyes had cobblestone-like papillae on the upper tarsal conjunctiva and corneal complications such as corneal ulcers, defect, or erosions that were refractory to conventional treatment of more than 2 weeks. Papillary resection with intraoperative 0.05% MMC application for 5 minutes on the palpebral conjunctiva was carried out in all eyes. Corneal and conjunctival findings were evaluated before and 1 week and 2 weeks after surgery. Brush cytology (BC) and evaluation of tear eosinophilic cationic protein (ECP) levels by radioimmunoassay techniques were performed as well pre- and postoperatively. Results: Corneal and conjunctival complications resolved in all patients within 7 days after resection. Postoperative tear ECP levels decreased significantly with papillary resection (P < 0.05). Concomitant brush cytology showed a significant decrease in the number of eosinophils and neutrophils following papillary resection (P < 0.05). Conclusion: MMC-aided papillary resection provided a dramatic decrease in ocular surface inflammation as evidenced by decrease in the number of inflammatory cells as well as tear ECP levels with a rapid improvement of clinical corneal and conjunctival findings.
